Why is there no safety on the at, everytime you strap it on your back it fires.

The original idea was that the user could choose to either carry it "unloaded" on his back or "loaded" in his arms, this was supposed to nerf it a bit by making it a bit slower to use and force the user to plan his attacks.
Sadly the users didn't really agree and many modified their AT4's with makeshift covers for the trigger. This forced us to install a protection for the trigger on all AT4's. It's still not intended to be carried loaded.

We have talked about adding a safety that could be engaged/disengaged by pushing the reload-button on a loaded AT4 and we will look into it for the next software update, hopefully together with some other nice features.

Also how can you hit your own car if you standing next to it while aiming at a car 50 meters away.

The AT4 uses IR-light to communicate between the AT4 and the receiver. To achieve a respectable range we have installed a rather powerful LED, this power sadly comes with some bad effects, one of them is that the lens scatters some of the light and creates a short range "shotgun" effect together with the main "beam", this shotgun beam can be reflected on things like carwindows and hit vehicles beside the user.

Video from old B14 which demonstrates the radio firing. Using baofeng UV-5R in 5W and somewhere 136-155Mhz although it didn't matter which frequency you used.

Thank you for the information, we will look into this, it should hopefully be a pretty simple fix. It is a bit weird that we hasn't heard about this earlier...
Thanks again and I hope this issue didn't ruin the game for you guys!

There should be some loud noise when using the BAVS units. Or something else to give away your position.
An at4/carlgustav etc isnt exactly silent when used.

The AT4 does make a sound, it is just kind of hard to make it loud enough to be heard when you are 50m+ away.
I have a suggestion that I have been thinking about for a couple of years now but hasn't had the chance to implement. I will try to explain it as well as I can and please tell me what you think.

Alternative 1A - Easier to implement
The plan is to add a simulated "lock on" function.
The AT4 will no longer fire as soon as you push the button, instead you will have to hold the firebutton down and track the target for a random time between 3-6 seconds (the time is random to force the shooter to actually track the target, this times will have to be tested and adjusted to see what works in practice). During this tracking mode, the summer will sound and a red LED will light up inside the lens-tube. The light is inteded to help warn the target vehicle and the sound is intended to alert any infantry nearby.
When the timer has elapsed the AT4 will fire.

Alternative 1B - Harder to implement
1B is quite similar to 1A but it also lights up the LED's on the targets receiver and alerts the target with a warning sound (for example a high frequency beeping) from the targets siren.
This is not just a nerf of the AT4 but it also gives the shooter the ability to check that the target is within range of the weapon.

This is not an official statement from BE, it's just a comment from a developer and builder of the system.

It would be great to make the BAVS receiver and the control box "undisconnectable" during the game. I mean the RJ-45 connector sealed by the crew.
We have had several incidents in field with red vehicles, that even after shooting 8 shots directly at the receiver (in-game) nothing happend and the next shot on a vehicle next to it was directly a correct hit.
So, I suspect some could disconnect the RG-45 connector during the engagement and connecting it back after the fight, so it keep working normally and a test shot shows system is working correctly. I will also forward this info th BE-crew once I've got back home to my video recordings and photo data

I understand that it is frustrating, but I personally believe in Hanlon's razor "Never attribute to malice that which can be adequately explained by stupidity."

It is easy to forget to connect your battery, to reset your receiver after respawn or accidently disconnect your sensor. If a player wants to cheat he or she will find a way to do it. It is, how ever, up to us to make it as easy as possible for players to follow the rules. And I realize that there are some "room for improvement". Currently we have the red flashing heartbeat LED's on the sensor board. If you see a vehicle without a flashing sensor, please kindly remind them to turn their receiver on.

as a driver i would like to have some sort of notification on low battery or sensor error, and a green led for system on.
you almost need a flashligt to se the display in a dark car during daytime.

A low battery notification would be nice but it would be very hard to accomplish since the batteries are supplied by the players, my advice would be to use one of the Lipo warning circuits.
A notification for a sensor error on the receiving box is also hard to achieve with the current hardware but the heartbeat LED on the sensor kinda fills that function.
We will look into the possibility to add a status LED on the box, we have already discussed having the blinking frequency of the heartbeat (on the sensor) increase the less health the vehicle has left, and mirroring this frequency on the receiver-box would be pretty neat.

But in the end it's all up to what the GM's want, we will bring it up.

Thank you both for your feedback, it is very valuable!

Thx for your reply, Grape.
We did checked and reminded the players after the fight (2 times actually with the same vehicle/team), but unfortunately for us, it was too late and we anyway went to respawn (and they continued the game, although they normally have been hit too, but okay, who am I to judge). One other vehicle took the hit when they saw their 2nd vehicle was destroyed (they had some issues with the receiver too, probably didn't reset after respawn). Thumbs up for this!

Thanks for a great system. As you self say, there is always a way to improve so we will be back and give you even more feedback next year

BAVS worked great this year.
They were even devided between GFM en TFC. Yes, the shop sucked but things like that happen. But it got fixed and who wanted one, got one.

The AT4 is still very powerfull and good explenation about the button and accident fires. I never tought that was the reason. Now i get it and it makes sense. I read the possible upgrades on the system. The 3-6 sec tracking would be a nice addition.

It would be nice to have limited shots, after your shots are gone, you would have to go and reload in base or on an 'ammo crate'. So you get 10 new shots.

Tracking would be nice for the BAAS, but perhaps not for the BAVS. AT4s are a ballistic weapon, you miss or you don't

Some form of flash would be a great addition, to give the rest of the convoy an idea where the shot came from and react accordingly. A warning signal would just lead to some real janky manouvres (or perhaps the top gunner 'leaning a certain way').

Limiting ammo is a personal favourite of mine. Endless AT ammo is a bit OP.

Radio interference should be easily solved by shielding the components.

Looking forward to next year, I hope we'll be able to make it work a bit better!

Well, the tracking is mainly meant to be a nerf for the AT4 so I don't think that we need to be completely realistic.
The locking LED's would make it a bit more visible when used in darkness and thus sacrifice stealth for the increased range.
Nerfing the AT4's could also potentially open up for a more varied arsenal of AT-weapons, for example HMG's with very weak individual "bullets" but relatively high rate of fire. Armour piercing sniper-rifles which are weaker than AT4's but more "sneaky".

Some form of flash would be a great addition, to give the rest of the convoy an idea where the shot came from and react accordingly. A warning signal would just lead to some real janky manouvres (or perhaps the top gunner 'leaning a certain way').

We will have to try some different solutions to find one that is fun, fair and safe for both the shooter and the shootee.
I just pray that we will be given the time and opportunity to do it.

Limiting ammo is a personal favourite of mine. Endless AT ammo is a bit OP.

We tried a physical key to limit the ammunition but those were lost/stolen every year so we gave up on that when the keys ran out. For some reason the rules still says:

The AT weapon must be reloaded by a Game-master in your base HQ with special key.

We will look into the possibility to load it with IR, perhaps we could try it on a couple of AT4's next year and see how it works. Perhaps making it work as anti-air missiles but giving it a magazine limit of 10 rockets and if it turns out well it could be expanded to the rest?

Radio interference should be easily solved by shielding the components.

Yes, I'm not worried about that either, it is a bit embarrasing though.
It kinda reminds me about the game in Graninge where a lot of battles were fought under the power-lines. And we got a number of reports about the BAVS system not working.
It turned out that enough current was induced into the ethernet wire from the powerline to confuse the receivers.
Well, you live and learn.

Thanks for your feedback!

Let me also add that what is written here are not promises but just my personal thoughts and opinions. We will have to see what BE wants to have done and what they want to prioritize.
